Introduction
• Reconfigurable devices for combined signal paths are technology enablers for Multi band, Multi mode, Software Radio and Multi standard Radios.
• Features for future multiradio devices:– Cellular: GSM/WCDMA/…– Wireless broadband: WLAN 802.11a/b/g/n/…– Short range connectivity: BT & UWB– Positioning: GPS/Galileo– Broadcast/TV: DVB-H
• Design considerations: – Architecture and system partitioning– Power management– IP blocks and interfaces

Radio Hardware Platform
• How many ASIC’s?• Single-chip radios or separate RF & BB ASIC’s• External RF components: antennas, filters, PA’s,
switches,…• How many modules?• Antennas distributed all over the product• Increased ASIC integration level not any more the only
driver in system architectural partitioning • Options
– Separate single-chip ASIC’s or system modules close to antenna– One centralized modem with distributed antennas– Something in between (including different choices)

A Fully Integrated SoC for GSM/GPRS in 0.13µm
• Crosstalk from the digital blocks into RF is one of the biggest concerns in single-chip transceivers.
• Substrate noise pickup, package crosstalk, magnetic coupling between the coils, and supply coupling degrade the RF performance.

• Cellular phones with embedded GPS engines will enable network-based positioning methods.• Assisted GPS solutions allow a direct migration path into 3G handsets besides being more accurate than cell tower-based ones.

DVB-H
• DVB-H is a new standard that is expected to be widely deployed in future mobile devices.
• The first DVB-H field trials were held in Europe and used the UHF band.
• DVB-H has also been targeted for deployment in the United States using L-band spectrum between 1670MHz and 1675MHz.
• There has also been discussion of reallocating European L-band DAB frequencies for DVB-H service.

Software-Defined Radio Receiver
• A software-defined radio (SDR) can tune to any frequency band, select any reasonable channel bandwidth, and detect any known modulation.
• While progress has been made on DSP and baseband functions for SDR, the low-power radio front-end has remained elusive.
• An ADC at the antenna which digitizes all bands simultaneously with equal fidelity will not be practical in the foreseeable future.
• Today’s mobile SDR receiver needs a wideband, linear RF front-end that can be tuned to any one channel at a time in the band from 800MHz to5GHz.

Conclusion
• Multi-Standard Radio Design is not only an ASIC level issue
• Hierarchical design and design abstraction are needed in system design
• Hybrid solutions cover numerous different options to realize Multi-Standard Radio
